That's why I said "Either state that you don't want an answer or just don't ask the question". It saves from headaches on both sides.

When you have an entire community involved in the creation of your lore, it must be explicitly stated what you do and don't want answered.

This isn't like a film, book, or triple-A videogame where you can just present mysteries and leave people wondering and give answers on your own time, people will try to answer your mysteries when you let them create so much of your world.
